The inner end of the body portion 2 of the v cock A is connected to'the. plug portion 15'.- through the threaded extension 16- on the ortion 2 engaging with the threaded aninur-r,

ar chamber 17 in the removable he'adlS forming part of said plug, and a -ircular passage-way l9v leads through said extension and valve seat 5 to the chamber 13 froni the chamber 17. Thenplug 15 is provided with g the tapered threaded exterior surface 20 at the inner end of its body portion 21 for en: with the head plate B of a boiler A circular passage-war 25 leads through the inner end of the portion 21 of the'plug 15ft; communicating with the chamber 23, ands through t e communicating with auxiliary valve 27. chamber 23 for en aging with a concave seat the chamber 17.

If'vdes'ired, another valve 31 can be used, as

shown in .Fig. 5, and this valve is'mounted upon the inner "end of the inner valve stem 29 a to act as an emergencvvalve. by being located beyond-the inner end of the body por- 96 thereon for fitting within the passage-ways vj 25 and 26 respectively, which stems are pro-Q v tion 21 fthe plug ortion- 15gahd-it-is removabljz connected tosaid stein the within valve;- en- J threaded opening I 31 "gaging with the threaded end 32 on said provided withithe stern; ;="1fhe',valve' 31 is I p I 33 for engaging with a concave atfii on the inner end of the body portion tlteplug 15 and aroundthe' passage- The use and o eration of my improved gage-cock is as to lows :With the parts of the coek A assembled and connected together so as to be applied to a boiler or other through the passage-ways and 26 around the valve 27 in the chamber 23 and its stems 29 and 30 into chamber 17, thence from said chamber through the passage-way 19 around the stem 30 into the chamberl3 and from this chamber through the discharge opening 14 leading from said chamber. In this o ening or unseating of the valve 4, the end 6 the outer stem 30 on the valve 27 can automatically bear against the end of said valve 4 from the pressure of thesteam or water passing around said valve 27 and thereby prevent said valve 27 from seating itself against its seat 28. When it is desired to close the valve 4 the handle wheel 12 is turned in the opposite direction, so that the stem 6 and said valve will be revolved in the same direction with said Wheel and in the opposite direction from that hereinbefore described, so that said valve will be seated on its seat 5 and thereby close off thesfsteam or water through the passage-ways 2 5, 26, and 19, and chambers 23, 17 and 13 to the discharge opening 14.

When it is desired to remove the main ortion 1 of thecock A for any purpose, sue 1 as the cleaning out of the same, or the repairing ofany of the parts thereof, the bonnet 3 carrying the valve 4 can be removed from the valve body 2 by unscrewing the same from said body through the disengaging of the threaded connection 3, which will expose said valve and its seat 5 for the cleaning, re-

pairing or other purposeintended, and when so removed, the steam or water is prevented from escaping through the plug 15 and body 2 by the pressure of thesame autonmtically seating the valve 27 against the seat 28.

When it, is desired to emove the valve or body portion 2 of the. geek A from the plug 15 for the further cleair'iing ol the said plug, the turning of the seat 5 for the valve 4, or for any other purpose, the said body portion is unscrewed from the head 18 on said plug through the threaded extension 16 on said plug disengaging with the threaded annular chamber 17, so that said portion 2 can be rcmoved, and when so removed, the steam or water is prevented from escaping by the automatic seating of the valve 2!) against its seat 28, in the manner above described.

In case it is desired to remove the head 18 for the turning of its valve seat 28, cleaning of the plug 15, or any other purpose, such head is unscrewed from the body 21 ot the plug 15 through its threaded extension 24 disengaging with the annular chamber 23 in said body, so that said head can be removed, and then the steam or water is prevented from escaping throu h said plug in the manner above describer 'by the pressure of the same against the valve 31, which will act to close said valve against the end of said plug and over the passage way 25 by the automatic seating of its face 33 within the seat 34 on said plug. If desired, the removable head .18 on the plug 15 can be dispensed with and the extension 16 on the l)0( y portion 2 can then carry the seat 28 for the valve 27, as is shown in Fig. 4, and if desired the valve 31 can also be dispensed with, as shown therein.

Various othermodifications and changes in the design, construction and operation of my improved gage-cock may be resorted to without departing from the spirit of the in vention or sacrificing any of its advantages.

It will thus be seen that my improved gage-cock is of great utility and of wide application in its use, and when in operation .all the parts are rendered easy of access and capable of removal for cleaning, repairing, changing or renewal. The construction of the stationary or plug portion of the cock will allow the valve movcmept therein to act as an agitator for the same and cock in order to prevent the lodging" of dirt and scale in the parts and thereby greatly assist in keeping the device clean at all times. When the device is in use in connection with a locomotive boiler, the plug portion will act as a safety valve for shutting off the hot water or steam, in case the cock is knocked oil or )ent to a degree through wrecks, etc. and thereby prevent injury or possible loss of life by scalding to persons in the cab or adjacent thereto. Very little cost is added to the usual form of gage-cock, as only the valve connection within the plug end of the cock is attached to the parts, and such valve movement being automatic in all its uses up labor or attachmmits are required to operate the same at any time. The parts when assembled in place are not exposed for injury or handling and being plwzllu'ztl l v formed of brass are not liable. to corrosion from the scale or water in the boiler. Practical eX- pcricnce With the cock has demmistratcd that when used on boilers it will operate. successl'ully at all times and will not require the banking ol the lire within the boiler, or the closing down of the boiler or engine, or the. laying oil of the loconmtivc, m case of the cleaning, repairing or renewal of any of the main parts of the cock.
